To [ZZZ whom it may coitceriz:

Be it known that 1, THEODORE 1). eat, of

Owego, county of Tioga, State of New York,

- have invented a new and useful Improvement in Grain-Drills, of whichthe following is a' full, clear, and exact description, reference beinghad to the accompanying drawings, 'making part of this specification.

My invention relates to an improvement in grain-drills, and moreespecially to that class in which a vertically-rotating feed-wheel withthe side casing is employed, whereby the size of the feed-channel andthe flow of the grain or other material contained in the hopper may beregulatedby simple and novel means; and it consists in providing thedischarge-opening with a pivoted laterally-movable gate, in formintended to exactly correspond with and slide through an opening in thecasing, said gate being hinged or pivoted, and provided with meanswhereby it is adapted to be rocked 011 its pivot, for a purposehereinafter set forth.

In the accompanying drawings, Figure 1 represents a perspective view ofso much of a grain-distributer as is necessary to show my improvements.Fig. 2 is a side elevation of the same; Fig. 3, a sectional view on theline as m, Fig. 2, and Fig. 4 a detail view, of the pivoted gate.

A represents a hopper of any ordinary or preferred form, to the base ofwhich are secured the upper flanged ends, A, of the distributerwheelcasing-plates. These ends A are secured to the hopper-box by means oflugs or projections a a, cast upon them, and extending upward at anangle corresponding with the inclination of the side walls of thehopper,

thro'ugh'which latter and the lugs referred to pass bolts for unitingthe parts. The casing B is made in twoparts, forming a chamber for thereception of the vertical distributor-wheel O, as shown, the parts ofsaid casing being connected by means of bolts 1) b at suitable points. Aperforation, b, isprovided in one side of the casing B for the passageof the main shaft D, upon which the distributerwheel 0 is mounted. Otherbearings for said shaft are provided in the form of pendent perforatedprojections A cast upon or secured to the sides of the hopper A. Theshaft D is grooved its entire length, and the distributerwheel 0, wheresaid shaft passes through it,

is provided with a small projection or key en terin'g said groove, thusserving to key the wheel to the shaft and insureits rotation therewith,at the'same time adapting the shaft tobe readilymoved when desired. Thedis.

tribnter-wheel O is of the form shown in section in Fig. 3tl1at is, itis provided with a U-shaped annular groove, 0, forming achannel for thepassage of the grain, and it also has an annular flange, c, surroundingits periphery, which is confined within and has its bearing against andbetween the side walls of easing B. An opening, B, is provided in thecasing B, to one side of the center of wheel 0, immediately at the mouthof a cup or tube, E, through which the grain, as it is delivered fromthe wheel,'is conducted to the ground. Another opening or slot, in theform of an arc of a circle, (designated by F,) is provided in thecasing, preferably below the center of the wheel 0, and a gate (shown indetail in Fi 4) is provided, adapted, when applied to said opening, tonearly iill the same. It consists of a piece, G, substantially of wedgeshape, but, more accurately speaking, of such shape as to conform to thecurvature of the groove 0 when it is inserted in the slot F. Thiswedgeshaped gate G has in rear of it a bar, G, to

which it is secured, said bar being provided on one end with a shank, g,which enters a socket, g", in the wall of the tube or cup E, and at itsother end with a tooth or point, 9, adapted to be engaged by a worm or ascrew, H, formed upon a shaft, H, supported in suit able bearingsprovided for that purpose. The bar G is supported at one end in thesocket g" and at the other in a slotted cross-bar, I, just beyond whichslot the tooth or point g is engaged by the worm or screw H. The shaft Hy is revolved by means of a crank, hand-wheel, or in any suitablemanner, and when so revolved, the worm or screw H being formed upon itor secured to it, the outer end, 9, of the bar G, by means of itsengagement with screw H, will be moved either toward or away from thecasing B, carrying with it the gate, which serves to either decrease orincrease the size of the channel 0 at that point. Thus, the size of thechannel being adjustable, by means of the gate G, the flow 'of grain canbe regu lated at will.

For insuring the passage of the grain in the channel 0 of the wheel 0,the walls of slid channel are roughened or provided with starts orindentations, as shown.

Having now described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. In a grain-drill, the combination, with a vertical distributing-wheelhaving a side groove or channel formed therein, of a laterally-swinginggate formed upon an arm pivoted outside of the distributing-wheel casingand adjustable transversely within and across said channel, forregulating the capacity of the channel, substantially as described.

2. In a grain-drill, the distributer-wheel casing provided with anorifice in its side, in combination with a laterally-swinging gateformed upon an arm pivoted outside of the distributing wheel casing andadjustable zo-through-said orifice transversely of the dismy hand.
